Support for array translations

[N1ebieski]

Fixes #300

This PR adds support for array translations for example:

resources/lang/en/validation.php:

'attributes' => [
    'question' => [
        'email' => 'email address',
    ],
]

Currently, the code:

__('validation.attributes.question')

shows:

Translation [validation.attributes.question] not found.Laravel Extension(translation)

but this key exists, it's only an array with nested elements.

This PR adds support for such keys for hovering and linking to the first element in the array. However, the value is not shown in the hover, because it's an array.

This code needs futher refactoring and testing.

Nice PR! 🚀

It is also interesting to apply it to the locale that I passed to the __() or trans() method

Example:

__('validation.attributes.question', locale: 'pt-BR')

Check the pt-BR folder this transcription
